4. 1. Handles: Some polybags have built-in handles,
usually made of the same plastic material as the bag.
Handles can be in the form of cut-out holes, loops, or
reinforced strips for easy carrying.

Bottom
2. Main body: This is the primary compartment of
the polybag, usually made of thin, flexible plastic
material. It provides the space for storing items.
3. Bottom: The bottom part of a poly bag is
typically referred to as the "bottom seal" or "bottom
closure." It is the sealed area at the bottom of the bag
that keeps the contents secure.

5. Printing or labeling area
Side seam
4. Printing or labeling area:
Polybags may have a designated space for printing
or labeling information such as branding, product
details, or instructions. This area is typically
located on the outer surface of the bag.
5. Side Seam: The side seam of
polybags refers to the sealed edge that
runs along the side of the bag, joining
the front and back panels together.
6. Supply Chain Stages of Polybag
Supplier resin distributed and delivered
Resin received in raw materials warehouse
Reception registered in purchasing and supplier paid
Resin sent to poly/plastic packaging production warehouse
Resin and shredded containers fed into receiver
Containers shredded by an operator

Resin is a material that is extracted from the secretions of plants and trees.
7. Over for fabricating poly/ plastic containers with 8 unit capacity

8. Some Proposed
Practicable Solutions
• Sustainability best practice has a
hierarchy of what to do with
waste: first remove, then reduce,
then reuse and only then start to
consider alternatives to landfill.

Contribute to greenhouse gas emissions, which contribute to climate change
and have negative impacts on the environment and human health.

13. Use biodegradable materials
Instead of using traditional plastic, consider using biodegradable
materials to make the bags
Instead of using traditional plastic, consider using biodegradable
materials to make the bags
Reduce the thickness of the bags
Add seeds to the bags
Make bags out of food waste
Use recycled materials
Provide disposal instructions
Use natural dyes
Another way to make single-use poly bags more sustainable is to reduce
the thickness of the bags.

Using recycled materials to make single-use poly bags can help reduce
the amount of waste generated by the production of new bags.

it's important to provide clear disposal instructions for the bags to help
customers dispose of them properly.

Some companies are experimenting with creating single-use poly bags
from food waste, such as fruit peels and vegetable scraps.

The bags more eco-friendly by adding seeds to the material, which will
allow them to grow into plants when disposed of in soil.

Consider using natural dyes to color the bags, instead of synthetic dyes.

14. Conclusion
Polythene is a easy to get material for our various
daily uses. Though it is available and cheaper it is
hazardous for our environment.
A clean and safe environment is necessary to live a
healthy life. If our environment get contaminated it
will be hard to survive. So, we should stop using
harmful elements such as polythene, plastic, PVC
etc to save nature. We should use natural elements
for sustainability of our day to day life.
